Filed: 1944-07-10
Abstract: 589,289. Condensers. TOBE DEUTSCHMANN CORPORATION. July 10, 1944. No. 13127. Convention date, Nov. 30, 1943, [Class 37] The capacitance of a condenser comprising conductor plates separated by insulating plates and housed in a container having stiffly ductile walls, e.g. of sheet steel, is adjusted by forcing the condenser plates together by gradually applying a pressure to a wall of the container until the desired capacitance is obtained. A portion of the wall is permanently indented by the pressure, to fix this capacitance without altering substantially the main dimensions of the container. For example, a container 5, housing a condenser, is filled with an oil and immersed in the oil between projections 13 and 15 on the bottom of a receptacle 12 and a platen 14 respectively. Pressure is applied gradually through the platen 14 until a meter 19, connected to the condenser terminals 6, indicates the desired capacitance. The projections 13, 15 indent permanently central portions of opposite walls of the container to fix this value of capacitance. The container, filled with oil, is then removed and the opening 10 is sealed with solder. The condenser may be of the wound or stacked-plate type.

Abstract: 861,599. Universal joints. COURTAULDS Ltd. May 1, 1958 [May 2, 1957], No. 13993/57. Class 80 (2). A universal joint between shafts 1, 2 comprises flexible sheet-metal rings 9 secured at their inner peripheries by welding, brazing, soldering or the like to collars 3 attached to the shafts and similarly secured by welding &c. at their outer peripheries to rigid rings 11 connected by a channel cross-sectioned ring 12 to form a torque transmitting tube. The collars 3 are attached to the shafts 1 by radially-inserted cotter pins 4. The rigid channel cross-sectioned ring 12 is secured to the rings 11 by bolts 13 which enable the ring 12 to be removed without disturbing the shafts 1, 2. The cotters 4 can then be with drawn and dismantlement of the joint completed. Set-screws carried radially by the collars 3 engage with lost-motion in holes (not shown) in the rings 11, so that should failure of one of the sheet-metal rings 9 occur, torque can still be transmitted through the joint. Alternatively, the collars 3 may be of square crosssection, to engage loosely in correspondinglyshaped holes in the rings 11 to obtain the same effect. The sheet-metal rings 9 may taper in cross-section or may be formed with ring-like waves. A number of sheet-metal rings may be connected together. Specifications 564,963, 733,885 and 763,258 are referred to.

Abstract: 450,719. High-tension switches; arcrupturing in switches. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. May 13, 1935, No. 14025. Convention date, May 15, 1934. [Class 38 (v)] The circuit - breaker described in Specification 444,042 is modified by arranging that the formation of the magnetic field is only effected shortly before the zero of the A.C. cycle, whereby a relatively weak field may be employed and the arc-energy is kept low. The arc set up between the electrodes a, b in the compressed-gas container is acted on by the field of a blow-out magnet d in the circuit of a vapour-discharge valve n, the grid m of which is energized from a current transformer i in the line h, such that the voltage on the grid disappears at current zero and allows energizing current to flow. A resistance r reduces the time-constant and enables the field to build up quickly, but this result may be effected by over-excitation. The source for the valve may be D.C., in which case it should be opened when the line current has been interrupted, or, as shown, an A.C. supply of a frequency different from that of the main supply may be employed. Full-wave rectification may be used in order to render the arrangement independent of the short-circuit current direction. When the line current is itself employed for producing the field, as by phase-splitting, the component producing the field is preferably in phase-quadrature with the actual line current and its wave-form is preferably that of a salient peak, Fig. 3 (not shown).

Title: Improvements in or relating to mechanisms applicable to hardness testing
Inventor: GREEN JACK RAYMOND
IPC: G01N3/00
Filed: 1959-04-24
Abstract: 903,018. Hardness testing. VICKERS RESEARCH Ltd. April 12, 1960 [April 24, 1959], No. 14064/59. Class 106 (2). [Also in Group XXIX] A micro-hardness testing apparatus comprises an indenter 6 connected to the housing 3 of an objective 8 by means of a flexible diaphram 14 so that the indenter 6 may be moved relative to the objective along the optical axis thereof. A moving coil 11 between poles 12 of a permanent magnet 13 may be actuated to move the indenter 6 first to a position adjacent the testpiece (not shown) and then to urge the indenter against the test-piece with a predetermined force so that a substantially impact-free indentation is made to be measured by the microscope which is attached to screw thread 5. In an alternative embodiment, Fig. 3, the indenter 45 and associated mountings 46, 48 are moved by pneumatic force. Impact free contact between the test-piece and indenter is assured by attaching a capillary tube to the inlet pipe 60. A pneumatic load generator, shown in Fig. 4, is suitable for use with the gauge shown in Fig. 3. The plunger 74 is initially moved into an enlarged portion 76 allowing chambers 67, 66, 89 to communicate with the atmosphere. The plunger 74 is then moved along the bore 67 compressing the air in chambers 66, 89 until the force of the compressed-air counteracts the downward force of a weight 96 on bellows 80 sufficiently to cause a valve body 83 to seal chamber 89 and rod 82 engages a contact 94 illuminating a lamp 94A. If the plunger is moved slightly further in each time the lamp lights, air escaping from chamber 89 through capillary 90 into the gauge of Fig. 3 will be replaced until the gauge and chamber both contain air at a pressure determined by the weight 96. Human errors in operating plunger 74 are eliminated in the pneumatic load generator shown in Fig. 5 in which a plunger 132 is spring-urged to contract or expand a chamber 135 on which weights 164-169 may act.
